Method and apparatus for configured grant regarding sidelink carrier aggregation in a wireless communication system

Abstract

Methods, systems, and apparatuses are provided for configuring sidelink (SL) configured grant configuration in SL carrier aggregation. A method for a first device in a wireless communication system can comprise receiving a first sidelink configured grant configuration, wherein the first sidelink configured grant configuration indicates and/or includes a first frequency information and one or more first SL resources, and performing one or more first SL transmissions via the one or more first SL resources on a first SL frequency indicated by the first frequency information.

What is claimed is: 
     
         1 . A method of a first device, comprising:
 receiving a first sidelink (SL) configured grant configuration, wherein the first SL configured grant configuration indicates and/or includes a first frequency information and one or more first SL resources; and   performing one or more first SL transmissions via the one or more first SL resources on a first SL frequency indicated by the first frequency information.   
     
     
         2 . The method of  claim 1 , further comprising:
 receiving a second SL configured grant configuration, wherein the second SL configured grant configuration indicates and/or includes a second frequency information;   receiving a signaling from a network node, wherein the signaling indicates one or more second SL resources, wherein the signaling is used for activating the second SL configured grant configuration; and   performing one or more second SL transmissions via the one or more second SL resources on a second SL frequency indicated by the second frequency information.   
     
     
         3 . The method of  claim 2 , wherein the second SL configured grant configuration is a Type 2 configured grant. 
     
     
         4 . The method of  claim 2 , wherein the second frequency information indicates an identity or an index associated with the second SL frequency; and/or
 wherein the second SL frequency is a second carrier frequency and/or a second SL Bandwidth Part (BWP) utilized for sidelink; and/or   wherein the first and the second SL frequencies are different SL carriers or SL BWPs.   
     
     
         5 . The method of  claim 1 , further comprising:
 receiving a second SL configured grant configuration;   receiving a signaling from a network node, wherein the signaling indicates a second frequency information and one or more second SL resources, wherein the signaling is used for activating the second SL configured grant configuration; and   performing one or more second SL transmissions via the one or more second SL resources on a second SL frequency indicated by the second frequency information.   
     
     
         6 . The method of  claim 5 , wherein the second SL configured grant configuration does not indicate and/or include the second frequency information. 
     
     
         7 . The method of  claim 5 , wherein the second SL configured grant configuration is a Type 2 configured grant. 
     
     
         8 . The method of  claim 5 , wherein the second frequency information indicates an identity or an index associated with the second SL frequency; and/or
 wherein the second SL frequency is a second carrier frequency and/or a second SL Bandwidth Part (BWP) utilized for sidelink; and/or   wherein the first and the second SL frequencies are different SL carriers or SL BWPs.   
     
     
         9 . The method of  claim 1 , wherein the first SL configured grant configuration is a Type 1 Configured grant. 
     
     
         10 . The method of  claim 1 , wherein the first frequency information indicates identity or index associated with the first SL frequency; and/or
 wherein the first SL frequency is a first carrier frequency and/or a first SL Bandwidth Part (BWP) utilized for sidelink.   
     
     
         11 . A method of a first device, comprising:
 receiving a first sidelink (SL) frequency configuration, wherein the first SL frequency configuration indicates and/or includes at least one first SL configured grant configuration; and   performing one or more first SL transmissions via one or more first SL resources indicated in the at least one first SL configured grant configuration on a first SL frequency indicated in the first SL frequency configuration.   
     
     
         12 . The method of  claim 11 , wherein when the first device has multiple SL frequency configurations comprising the first SL frequency configuration, the first SL frequency configuration indicates and/or includes the at least one first SL configured grant configuration. 
     
     
         13 . The method of  claim 11 , wherein when the first device has only one SL frequency configuration, which is the first SL frequency configuration, the at least one first SL configured grant configuration is not included or indicated in the first SL frequency configuration. 
     
     
         14 . The method of  claim 11 , wherein when the first device has only one SL frequency configuration, which is the first SL frequency configuration, the at least one first SL configured grant configuration is included or indicated in a SL configuration other than the first SL frequency configuration. 
     
     
         15 . A method of a first device, comprising:
 receiving a first sidelink (SL) configuration, wherein the first SL configuration indicates and/or includes at least a first SL scheduling configuration associated with a first SL frequency and a second SL scheduling configuration associated with a second SL frequency;   performing one or more first SL transmissions via one or more first SL resources, on the first SL frequency, indicated in a first SL configured grant configuration in the first SL scheduling configuration; and   performing one or more second SL transmissions via one or more second SL resources, on the second SL frequency, indicated in a second SL configured grant configuration in the second SL scheduling configuration.   
     
     
         16 . The method of  claim 15 , wherein the first SL configuration indicates and/or includes at least a first SL frequency configuration and a second SL frequency configuration; and
 wherein the first SL frequency configuration indicates the first SL frequency and the second SL frequency configuration indicates the second SL frequency.   
     
     
         17 . The method of  claim 15 , wherein a number of SL scheduling configurations is the same as a number of SL frequency configurations for indicating SL frequency; and/or
 wherein association between SL scheduling configuration and SL frequency is based on one-to-one mapping between SL scheduling configuration and SL frequency.
